Since Gorochov compared the type of this species with a paratype of P. lineaticeps (?= P. formosanus) (Gorochov, 1988, 1997), we believe that they are different species. But we doubt that there would be an incorrect identification on material collected from China, which were mentioned in Gorochov’s works. He discussed three specimens collected from Guangdong Province, China (three females, China, Prov. Guangdong, Guangzhou ‘Canton’, Mell S.V., deposited in Natural Museum of Humboldt University, Berlin) and he identified two of them which bear dark coloration as P. fuscus and one colored light as P. lineaticeps (?= P. formosanus) (Cigliano et al., 2020; Gorochov, 1988, 1997). All specimens we collected in China (see details in materials examined above) were identified as P. fuscus by features of male genitalia (accessory structure of epiphallus of this species armed with hook-like apex) and they are vary in coloration, of them some ones are colored dark while others colored light. Thus, we do not think it was correct to identify those three females (in Natural Museum of Humboldt University) based on their coloration and, to a great extent, we think they are probably the same species as we have here. In addition, there is a problem on illustrations of P. lineaticeps (?= P. formosanus) in Gorochov (1997: Figs 169–178), since these figures were drawn based on specimens of Province Vinh Phu, Vietnam but not the type specimen. If the author did not check the genitalia of them and only judged them by their coloration, we could assume these specimens bear light coloration should not be the species of P. lineaticeps (?= P. formosanus). But, in this case, how do we understand the difference, such as structure of metanotal gland, between species of P. fuscus and P. lineaticeps (?= P. formosanus) as indicated in Gorochov (1997). Our male specimens possess similar genitalia and they vary not only in coloration (Fig.15) but also in structure of metanotal gland (Fig. 16). Thus, we still believe it is reliable to use genitalia features to identify the species of the genus, but, at least for now, not coloration and some others mentioned in literature (Gorochov, 1997)., Published as part of He, Zhixin & Ma, Libin, 2021, Crickets of the subfamily Itarinae Shiraki, 1930 (Orthoptera: Gryllidae) from China with description of a new species and distribution and critical notes on other species, pp. 382-408 in Zootaxa 4942 (3) on page 404, DOI: 10.11646/zootaxa.4942.3.4, http://zenodo.org/record/4604363, {"references":["Gorochov, A.

Parapentacentrus formosanus Shiraki, 1930 Parapentacentrus formosanus Shiraki, 1930: 224; Gorochov, 1985: 19; Ma, 2011: 97; Ichikawa, et al., 2000: 273 Pseuditara lineaticeps Chopard, 1969: 317, synonymized by Ichikawa, et al., 2000: 273 Holotype information. Type locality: China: Taiwan, Arisan (April?), Musha (May?, June?). Deposited in National Taiwan University. Material not examined. Remarks. Shiraki primarily described and illustrated coloration and many characters that are possessed by most species of the genus, and, especially, he did not study and aspects of male genitalia (Shiraki, 1930). Thus, subsequent researchers could only identify the species by coloration and the minor considerations of ovipositor length (Gorochov, 1997). In 2000, the male genitalia of this species were illustrated, meanwhile, P. lineaticeps was placed as junior synonym of P. formosanus (Ichikawa et al., 2000). Although no one disputes this conclusion (Cigliano et al., 2020; Gorochov, 2008), we still have some questions based on this species as follows: (1) Illustrations of the genitalia, were not accompanied by which specimen was used and where it collected from. Thus, we question whether the specimen used for genitalia drawing of P. formosanus is the type or the material collected from the type locality; (2) Regarding synonymous relationship between P. formosanus and P. lineaticeps, no explanation for this change was proveded. We discovered that the the examined type specimen of P. lineaticeps is female (Female, Myanmar, Nam Tisang, alt. 3000 ft., NHM, Kingdon Ward) (Ichikawa et al., 2000), thus we surmise this combination was based solely on external features and in all probability the primary character was coloration. Indeed, after examining specimens collected from Fujian (adjacent to Taiwan), Guangxi and Hongkong (adjacent to Vietnam and Guangzhou), and Xizang (adjacent to Myanmar), we found all the males possessed similar genitalia and had two colour morphs, light brown or dark brown. Based on our experience in the field, we conclude most individuals are one species and with two coloration morphs since we collected them in same time and same place. We feel that only one species is involved., Published as part of He, Zhixin & Ma, Libin, 2021, Crickets of the subfamily Itarinae Shiraki, 1930 (Orthoptera: Gryllidae) from China with description of a new species and distribution and critical notes on other species, pp. 382-408 in Zootaxa 4942 (3) on page 402, DOI: 10.11646/zootaxa.4942.3.4, http://zenodo.org/record/4604363, {"references":["Shiraki, T.

Ornebius aurumalas, He, Zhang & Ma sp. n. Figs 3–5 Type materials. Holotype. China: Male, Guangdong, Nanling National Nature Reserve, 31st October 2014, Zhang Tao coll. Paratypes. 5 males, Guangdong, Nanling National Nature Reserve, 31st October 2014, Zhang Tao coll.; 2 females, Guangdong, Nanling National Nature Reserve, 31st October 2014, Zhang Tao coll. (SNNU). Description. Male. Typical body of genus. Head small. Rostrum swelling with furrowed distinctly, slightly wider than antennal scape; maxillary palpus with apical segment distinctly widened; third and fifth segments of equal length, a little shorter than the fourth one. Fore tibia internal tympanum large and rounded, without external tympanum. Pubescent joint of head and pronotum. Pronotum is longer than width, almost three times longer than head; posterior margin broad and convex with white scales roundly. Tegmen mostly exposed with pubescent on posterior margin (Fig. 4A). Hind femur 1.1 times longer than hind tibia, with sparse hairs; hind tibia 1.9 times longer than hind metatarsus with two rows of denticles about 26–28 teeth each. Cerci pubescent, different length. Abdomen: Supra-anal plate with last abdominal tergite and epiproct distinctly separated by a transverse suture and bristles along the suture; last abdominal tergite with long basolateral bristles, apex with a pair of short and roundlywide lobes, emarginate in the middle (Fig. 4J). Genitalia: Male phallic complex with medial valve curved to a spiral in basal part with its base forming an axis in the centre of the spiral (Fig. 4E). In dorsal view, two sides of the axis centre strongly projecting perpendicular of the spiral and pale yellow (Fig. 4C). In ventral view, internal sclerite of medial valve with two elongated and straight narrow rods (Fig. 4D), gently curved at the base in lateral view (Fig. 4E); apex widen into a transverse spade-like lobe, apical margin truncated and not surpass the apex of ejaculatory duct (Figs 4F & G). Ejaculatory duct basal part strongly curled into a large spiral and spermatophore sac massive. Female. Similar to male but apterous (Fig. 4B). There are two symmetrical irregular depressions on the surface of pronotum. Hind femur is 1.2 times longer than hind tibia. Abdomen: Supra-anal plate triangular with apex truncate, with a deep groove in middle. Ovipositor curved and smooth (Figs 4H & I). Colouration. Dorsal view, head and pronotum reddish-brown. Tegmen is yellowish with black posterior margin. Hind femur internal white. Abdomen brown with yellow scales on the surface. Cerci yellow. Calling song. Echeme sequence period 16–17 s, echeme sequence duration 2–4 s with 12–13 s echeme sequence interval. Each echeme sequence includes 5–10 echemes. Each echeme period 0.4– 0.45 s, echeme duration 0.05– 0.1 s with 0.35 s echeme interval. Each echeme includes 2 syllables. Echeme sequence rate is about 5 syllables/s. The dominant harmonic peak observed in the spectrogram is 5.8–6.2 kHz (Fig. 5). Measurements. Male: BL 10.92, PL 3.92, PW 3.19, TL 3.35, TW 3.84, HFL 5.66, HTL 4.73, HML 1.67; Female: BL 8.34, PL 2.82, PW 2.62, HFL 5.49, HTL 3.36, HML 1.84, OL 4.63. Etymology. The name refers to its colouration of tegmen. Remarks. This species is similar to O. formosanus, O. yunnanensis, O. lunam and O. panda in body colour and male genitalia. This species however differs from all the above species by the central lobe of phallic complex’s morphological structure, shape and size of supra-anal plate and body characteristic of female. It even differs from O. panda in tegmen and size of genitalia, its dark brown area rather small and genitalia rather large. It is also similar to O. polycomus in male genitalia, but different in body colour., Published as part of He, Zhixin, Ma, Ge, Long, Jifeng, Wang, Yan, Zhang, Tao & Ma, Libin, 2021, Taxonomy of scaly crickets (Orthoptera: Mogoplistidae: Mogoplistinae) from China: five new species groups and three new species of the genus Ornebius Guérin-Méneville, 1844, pp. 72-94 in Zootaxa 4942 (1) on pages 76-78, DOI: 10.11646/zootaxa.4942.1.3, http://zenodo.org/record/4596135
